The Quadratic Formula

Examples

Bellwork 9/09

Complex Conjugates

We cannot leave i’s in the denominator. So, multiply the top and bottom of the fraction by the conjugate of the denominator to eliminate the imaginary part

Bell work

Monomials Monomials—a number, a variable, or a product of a number and one or more variables.

Coefficient—the number in front of a variable. Degree—the sum of the powers of the variables in a monomial.
